**Kosmos 320** ([Russian](/source/Russian_language): Космос 320 meaning *Cosmos 320*), also known as **DS-MO No.3** was a technology demonstration [satellite](/source/Satellite) which was launched by the [Soviet Union](/source/Soviet_Union) in 1970 as part of the [Dnepropetrovsk Sputnik](/source/Dnepropetrovsk_Sputnik) programme. Its primary mission was to demonstrate orientation control by means of an [aerodynamic skirt stabiliser](https://en.wikipedia.org/w/index.php?title=Aerodynamic_skirt_stabiliser&action=edit&redlink=1).[1] It also carried an optical research payload for the [Soviet Armed Forces](/source/Soviet_Armed_Forces).

## Launch

It was launched aboard a [Kosmos-2I](/source/Kosmos-2I) 63SM rocket[2] from [Site 86/4](https://en.wikipedia.org/w/index.php?title=Kapustin_Yar_Site_86&action=edit&redlink=1) at [Kapustin Yar](/source/Kapustin_Yar). The launch occurred at 10:59:58 UTC on 16 January 1970.[3]

## Orbit

Kosmos 320 was placed into a [low Earth orbit](/source/Low_Earth_orbit) with a [perigee](/source/Apsis) of 247 kilometres (153 mi), an [apogee](/source/Apsis) of 326 kilometres (203 mi), 48.4 degrees of [inclination](/source/Inclination), and an [orbital period](/source/Orbital_period) of 90.2 minutes.[1] It [decayed](/source/Orbital_decay) from orbit on 10 February 1970.[4] Kosmos 320 was the second of two [DS-MO](https://en.wikipedia.org/w/index.php?title=DS-MO&action=edit&redlink=1) satellites to be launched. It was preceded by [Kosmos 149](/source/Kosmos_149), which was launched in March 1967.[1][5]
